1 General safety precautions
WARNING
Tear apart and throw away plastic packaging bags so that
nobody, especially children, can play with them. Possible
risk: suffocation.
DANGER: RISK OF BURNING
▪ Do NOT touch the refrigerant piping, water piping or
internal parts during and immediately after operation. It
could be too hot or too cold. Give it time to return to
normal temperature. If you must touch it, wear
protective gloves.
▪ Do NOT touch any accidental leaking refrigerant.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
NOTICE
▪ Do NOT place any objects or equipment on top of the
unit.
▪ Do NOT sit, climb or stand on the unit.
In accordance with the applicable legislation, it might be necessary
to provide a logbook with the product containing at least: information
on maintenance, repair work, results of tests, stand-by periods,...
Also, at least, following information must be provided at an
accessible place at the product:
▪ Instructions for shutting down the system in case of an emergency
▪ Name and address of fire department, police and hospital
▪ Name, address and day and night telephone numbers for
obtaining service
In Europe, EN378 provides the necessary guidance for this logbook.
1.2.2
Installation site
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit's weight and
vibration.
▪ Make sure the area is well ventilated. Do NOT block any
ventilation openings.
▪ Make sure the unit is level.
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where there is a risk of fire due to the leakage of
flammable gases (example: thinner or gasoline), carbon fibre,
ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
1.2.3
Refrigerant
If applicable. See the installation manual or installer reference guide
of your application for more information.

NOTICE
Make sure refrigerant piping installation complies with
applicable legislation. In Europe, EN378 is the applicable
standard.
NOTICE
Make sure the field piping and connections are not
subjected to stress.
WARNING
During tests, NEVER pressurize the product with a
pressure higher than the maximum allowable pressure (as
indicated on the nameplate of the unit).
WARNING
Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:
▪ Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.
▪ Toxic gas may be produced if refrigerant gas comes
into contact with fire.
WARNING
Always recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
▪ When the refrigerant system is to be opened,
refrigerant must be treated according to the applicable
legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant
may only be charged after performing the leak test and the
vacuum drying.
▪ In case re-charge is required, refer to the nameplate of the unit. It
states the type of refrigerant and necessary amount.
▪ The unit is factory charged with refrigerant and depending on pipe
sizes and pipe lengths some systems require additional charging
of refrigerant.
▪ Only use tools exclusively for the refrigerant type used in the
system, this to ensure pressure resistance and prevent foreign
materials from entering into the system.
▪ Charge the liquid refrigerant as follows:
If
A siphon tube is present
(i.e., the cylinder is marked with
"Liquid filling siphon attached")
Then
Charge with the cylinder upright.
